Duck and cover Chris Pratt: Jennifer Lawrence is on the war path and has access to a bus. OK, don't stress that much, she probably won't run you over, but she is definitely getting revenge for your little social media prank. In case you missed it, Pratt spent the first few weeks of the Passengers press tour cropping Lawrence out of his selfies and group pics, banking on the fact that the Instagram-less actress would be none the wiser.

But Lawrence has finally wised up and is not just going to take this prank war sitting down. During Jimmy Kimmel Live on December 12, the Oscar-winning actress decided it was time to show Chris what it's like to feel the wrath of J.Law.

"What kind of person are you?" Kimmel asks. "Are you the kind of person who's going to take this and just let this sort of thing happen and let Chris keep [abusing] you? Or are you going to do something about it?"

"F-ck it, I'm gonna do something about it," she tells Kimmel, before storming off the set, vengeance in her eyes.

Armed with cans of spray paint, Lawrence and the late-night host defaced a Passengers ad on the side of a Starline Tours bus (filled with thrilled tourists); they even give the actor devil eyes and turn his name into "Chris Rat," among other splendidly childish things.

Of course, Lawrence doesn't have an Instagram to document her antics, but it seems Chris tunes into Kimmel's show nightly. After the episode aired he tweeted an ominous message:

Unfortunately it seems Pratt has not yet learned not to mess with his co-star—lest she put an end to what has been a beautiful press tour together, involving insult wars, German speaking, and even magic tricks. Chris and Jennifer, you two are a terrifying delight.
